How we checked these dates
We read every date off the district's own calendar twice: once from the PDF's text and once from the image, line by line. Then we checked the June half days and the last day against the SLCS District Calendars page and the SLCS events calendar. The other dates rest on the district's calendar alone.
Every weekday on this page matches its date. If the district changes its calendar, its page is the final word.
